“Playing god by reducing people to the sum of their parts”? I think this just means it destroys people’s perception of us being some all-important special beings that exist with some divine purpose. You pick anything apart and you know it’s all similar or the same. Organs, cells, DNA, molecules, it all makes a person, or living organism in general. We’re all “animals” to put it that way, kind of making the word redundant. Everything just has it’s organic matter organized differently.
